The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X200-10S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 10 mm range without swapping the cylinder. Ø63mm bore, 200mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X200-10S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke, built around a robust 63 mm bore. Its rear-cap adjusting screw provides a 10 mm range to fine-tune the stroke end, making it ideal for commissioning and process tweaks without swapping the cylinder. The integrated magnet allows direct mounting of CMSG/DMSG/EMSG sensors for precise end-of-stroke detection.
With a 20 mm diameter piston rod and PT1/4 ports, this cylinder delivers a substantial 1559 N of push force at 0.5 MPa, scaling up to 2805 N at the maximum operating pressure of 0.9 MPa. The 28 mm air cushion at each end ensures quiet, controlled deceleration, even under high-cycle conditions. Its tie-rod construction and 197 mm body length (A dimension) provide a durable, serviceable platform for industrial automation tasks.

Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Related types: SC (single rod, fixed stroke), SCD (double rod), SCT (multi-position). SCJ mounting: Basic, FA, LB, TC, TCM1. Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
The 10 mm rear adjustment screw allows technicians to precisely dial in the stroke end position during machine commissioning, eliminating the need for shims or external hard stops.
Quickly adapt the cylinder's stroke for different product sizes on a packaging or sorting line. The adjustable stop enables a fast format change without mechanical disassembly.
In high-cycle clamping or pressing fixtures, the adjustable stroke can be used to take up mechanical wear over time, maintaining consistent clamping force and position without replacing the actuator.
Choose the SCJ63X200-10S when you need a 200 mm nominal stroke with the ability to dial back the end position by up to 10 mm for precise setup. If your application requires more force, stepping up to the 80 mm bore provides 2513 N of push at 0.5 MPa. For a simpler, fixed-stroke solution where adjustment is not needed, the standard SC63X200 is the direct alternative.
This model is a direct replacement for any AirTAC SCJ63X200-10S cylinder with a PT port and built-in magnet. For strokes of 300 mm or longer, be mindful of side-loading on the 20 mm rod; an external guide or a switch to a guided cylinder is recommended to prevent rod bending and ensure long seal life.
Adjustable-stroke checklist
The push force is 1559 N at 0.5 MPa and reaches 2805 N at the maximum operating pressure of 0.9 MPa. The pull force is slightly lower, at 1402 N at 0.5 MPa, due to the area of the 20 mm piston rod.
Yes, the SCJ63X200-10S has the same bore, port size (PT1/4), and mounting footprint as the SC63 series. It is a direct dimensional replacement, with the added benefit of the 10 mm adjustable stroke feature and a built-in magnet for sensor mounting.
